Last night she told me she recently has felt nothing towards me
More than likely her hormones making her feel a bit more detached. This could come & go throughout the pregnancy & isn't a direct reflection on you.
There's usually not enough time for DP & I, but during pregnancy I probably could've done it alone.
I'm wanting to be more active in the bedroom but she's never been overly excited about it
Lack of drive was my first symptom. I don't know if it's to do with your body already achieving what it needs to from sex. It came back but now I'm on the last stretch, even if I want to I'm too tired.
Sickness, nausea, tiredness, painful boobs, bloating, irritability, sore back, restless legs. 24/7 hangover a lot of the time. Not to mention the physical changes to her appearance. I've hardly ate & I'm fat! She might not be feeling herself & is probably feeling like she's hungover 24/7.
The last thing she needs is to feel pressured or worried this will be an issue in her relationship when she has everything else to deal with. She needs to be supported & will have sex when she's ready. Also, sometimes it causes irritation & bleeding which just adds more worry.
As I said, this isn't a reflection on you. This is all just a symptom of being pregnant. Be supportive & refrain from doing/saying anything that will cause a real problem. This is just standard stuff as many on here will tell you. She has a lot to deal with physically & mentally. Let her know you're there for her, help her out
